example 1

[0091](A) The compounds represented by the formulae (I) to (III), (B) surfactants and (C) chelating agents were used as shown in Table 1 to produce various agricultural chemical enhancers.

[0092]Each of these agricultural chemical enhancers was dissolved in ion exchange water in a concentration of 0.02% by weight. Using the resulting 0.02 wt % diluted solution, a Roundup liquid agent (containing 41% by weight of an effective component as a glyphosate isopropylamine salt) which was a commercially available herbicide and an aqueous Herbiace solvent (containing 20% by weight of an effective component as bialaphos) were respectively diluted at a dilution of 1:300, to obtain two agricultural chemical compositions on one effective component.

[0093]Crabgrass seeds were planted in a pot having an inside diameter of 12 cm and filled with a fertile soil sampled from a paddy field for a test in a greenhouse, river sand and commercially available culture soil in a ratio of 7:2:1 (weight ratio) to...

example 2

[0096]25 female mites (Tetranychus kanzawai Kishida) per division were implanted on a leaf disk of a green bean by a 4-times-recurrent backcross method and then incubated at 25° C. for 24 hours. As the leaf disk, a circular one having a diameter of 4 cm was used. After that, the whole of the leaf disk was dipped in a test solution for 5 seconds and then taken out of the test solution and allowed to stand at 25° C. for 48 hours. Then, the condition of the mites was observed to find miticidal ratio based on the case of the untreated division (see the equation shown below). As the miticide, an Osadan wettable powder 25 (containing 25% by weight of an effective component as fenbutatin oxide) diluted at a dilution of 1:2000 was used and the same one that was used in Example 1 was used as the agricultural chemical enhancer. The agricultural chemical enhancer was used such that the concentration of the effective component thereof in the diluted solution was adjusted to 0.1% by weight. Also...

example 3

[0098]The whole of a leaf disk of a green bean was dipped in a test solution for 5 seconds, taken out of the test solution and dried in air. Then, 10 rice planthopper larvae of third instar which had been incubated in advance were put on a leaf disk and incubated at 25° C. for 10 days. The number of dead rice planthopper was observed by the naked eye to certificate the potency of the insecticide. As the leaf disk, a circular one having a diameter of 4 cm was used. The test was repeated ten times and the insecticidal ratio was calculated in the same manner as in the case of the miticidal ratio. As the insecticide, an Aproad wettable powder (containing 25% by weight of an effective component as buprofezin) diluted at a dilution of 1:2000 was used and the same one that was used in Example 1 was used as the agricultural chemical enhancer such that the concentration of the effective component thereof in the diluted solution was adjusted to 0.025% by weight. Also, at the same time, the SP...

Abstract

The invention provides an agricultural chemical enhancer and an agricultural chemical composition which are safely used for crops without any phytotoxicity, have a potency enhancing action on various agricultural chemicals and promote the growth of a plant body to be intended to be grown. The invention relates to an agricultural chemical enhancer comprising at least one type selected from a specific alcohol compound, an ether compound and an ester compound.

Description

[0001]This application is the national phase under 35 U.S.C. § 371 of PCT International Application No. PCT / JP01 / 11142 which has an International filing date of Dec. 19, 2001, which designated the United States of America.TECHNICAL FIELD[0002]The present invention relates to a novel agricultural chemical enhancer and a novel agricultural chemical composition.BACKGROUND ART[0003]Agricultural chemicals including insecticides, fungicides (or bactericides), herbicides, miticides and plant growth regulators are used in the formulations such as emulsifiable concentrates, wettable powders, granules, dust formulations and suspension concentrates (flowable). At this time, various ideas on the qualities of formulations are carried out to draw out the effect of a technical material of agricultural chemical. However, it is difficult at present to more enhance the effect of an agricultural chemical by devising formulations. Also, because it is more difficult to develop a new agricultural chemica...
